How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Temperature Range: 0° to 170° F
Tubing: Use with firm (Durometer 95A-45D) polyethylene plastic or polyurethane rubber
Specifications Met: ISO 14743, except polybutylene plastic fittings

Insert tubing into these fittings and an internal gripping ring and O-ring hold the tubing tight. They are also known as instant fittings. To disconnect, push on the release ring and pull the tubing out of the fitting. Fittings have good corrosion resistance.

Identification rings (sold separately) snap over the release ring so you can color-code your lines.

Clips (sold separately) align and organize your tubing and fittings.

Nickel-Plated Brass Push-to-Connect Tube Fittings for Air

For Use With: Air, Lubricated Air
Temperature Range: 0° to 140° F, except plugs and straight connectors are 32° to 140° F
Tubing: Fittings with Release Ring and Fittings with no Release Type: Use with firm or hard (Durometer 95A-60D) nylon plastic, polyethylene plastic or polyurethane rubber
Fittings with Release Sleeve: Use with firm or hard (Durometer 95A-60D) polyethylene plastic or polyurethane rubber

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings. Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. To disconnect, push on the release ring or sleeve and pull the tubing out of the fitting.

Fittings with release sleeve are easier to disconnect than fittings with a release ring because they are seamless and won't collect dirt and debris.

Vibration-Resistant Precision AN 37° Flared Fittings for Stainless Steel Tubing

For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
Temperature Range: -320° to 500° F
Tubing: Use with seamless 304 or 316 stainless steel
Specifications Met: See Table

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications. The threads on the tube end are Class 3A and adhere to tighter tolerances than other 37° flared fittings. They are made to exact AS (formerly AN) specifications and provide a tight metal-to-metal seal on tubing that is flared to 37°. Fittings are 316 stainless steel for excellent corrosion resistance. They require a nut and a sleeve (ferrule) for each tube end. Nuts and sleeves are sold separately.

45° Flared Fittings for Copper and Brass Tubing

Temperature Range: -65° to 250° F
Tubing: Use with seamless brass and copper that meets ASTM B280
Specifications Met: SAE J512, SAE J513, UL Listed, except socket-connect fittings and fittings with BSPT thread meet SAE J512 and SAE J513 only

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They require a nut (sold separately) for each tube end. Fittings are also known as refrigeration and SAE fittings. They are brass for good corrosion resistance.

NPTF (Dryseal) threads are compatible with NPT threads.

Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.

Precision Compression Fittings for Copper Tubing

For Use With: Air, Cutting Oil, Ethyl Alcohol, Fuel Oil, Gasoline, Hydraulic Fluid, Isopropyl Alcohol, Mineral Oil, Natural Gas, Steam, Water
Temperature Range: -40° to 350° F
Tubing: Use with seamless copper that meets ASTM B68, ASTM B75, or ASTM B88
Compatible With: Parker CPI

Made to tighter tolerances than other compression fittings, these are designed for high-precision applications. They are also known as instrumentation fittings and flareless fittings. They come with a nut and a single sleeve (ferrule). The sleeve bites into tubing as you tighten the nut to create a strong seal. The nut has a molybdenum disulfide coating that acts as a lubricant for easy installation. Fittings are brass for good corrosion resistance.
